Ever wondered what the difference is between a test scenario and a test case? π€ Letβs break it down with some simple definitions and real-world examples that make it super easy to understand!
Whatβs a Test Scenario? π
A test scenario is like a big-picture description of what needs to be tested. Think of it as a high-level outline that represents a feature or functionality of your software. Itβs usually based on business requirements, like βUser should be able to log in with a valid username and password.β
Basically, itβs a blueprint that will later be broken down into multiple test cases.
Whatβs a Test Case? π
Now, a test case is where we get into the nitty-gritty details. Each test case is a set of inputs, conditions, and expected outcomes that a tester uses to verify if a feature is working as expected. Itβs a checklist for testers to make sure everything is working as planned.
β’ Test Case Example:
β’ Inputs: Enter a valid username and password.
β’ Condition: User is on the login page.
β’ Expected Outcome: User successfully logs into the system.
Test cases are created based on test scenarios, and they go through a formal review process to make sure everything is covered before testing begins.
Positive vs. Negative Test Cases π οΈ
Hereβs where we take it up a notch:
1. Positive Test Case:
β’ Checks if the system does what itβs supposed to do.
β’ Example: Logging in with the correct username and password should take you to the home page.
2. Negative Test Case:
β’ Checks if the system behaves as it shouldnβt (i.e., it catches errors gracefully).
β’ Example: Entering an incorrect username or password should show an error message saying βInvalid credentials.β
In other words, positive tests validate the βhappy pathβ π, while negative tests ensure that the software can handle errors without breaking! π¬
Key Differences at a Glance:
β’ Test Scenario: High-level description of what needs to be tested, like a story or use case.
β’ Test Case: Detailed steps for testing, with inputs and expected outcomes.
